ECE 2006 UMD Fall, 2014 NAME: _________________________ Quiz 1: 20 Points – Due 9/8/2014 – Show Work for Partial Credit A time varying electric current, I(t), is described in a piecewise linear fashion as shown below. Knowing that the relationship between charge and current is I(t) = d q(t)/ d t, find the following: a) (5 pts) Write the set of equations that describe the current algebraically as a function of time b) (10 pts) Write the set of equations that describe the charge, q(t), associated with this current (Assume that the initial charge, q(0), is -2.5 Coulombs) c) (5 pts) Compute the charge at 4 Seconds, q(4). d) (5 pts) Sketch q(t) Scott Norr Page 1 7/1/2016
